feat: updateEmail

🚀 Feature: Add updateMessage API to Messaging Module
✅ Summary
This PR introduces the updateMessage method in the Messaging class, allowing users to update an existing email message using Appwrite's Messaging API. It aligns with the structure of other official Appwrite SDKs and provides full parameter validation, error handling, and testing via an example.

📄 Description
✨ Public Method Added in Messaging.hpp
cpp
Copy
Edit
/**

• @brief Update an email message by its ID.
• @param messageId Unique message identifier
• @param subject New subject of the email
• @param content Updated content/body of the email
• @return JSON response string from the server
• @throws AppwriteException if parameters are invalid or request fails
  */
  std::string updateMessage(
  const std::string& messageId,
  const std::string& subject,
  const std::string& content
  );
  🔧 Implementation in Messaging.cpp
  Validates parameters (messageId, subject, content)

Constructs the JSON payload manually

Makes a PATCH request to the endpoint:

swift
Copy
Edit
/messaging/messages/email/{messageId}
Handles response and throws exception with details if request fails

💡 Example Added
examples/messaging/messages/updateMessage.cpp

Demonstrates:

Creating an Appwrite instance

Calling updateMessage(...) with real inputs

Proper error catching and output

🛠️ Makefile Updated
Added target to build and run updateMessage.cpp:

bash
Copy
Edit
make updateMessage
make run-updateMessage
🧪 Tested With
✅ Valid messageId (success)

⚠️ Invalid/expired messageId (handled 400 & 404 errors)

✅ Windows/Linux curl compatibility

❗ Handles failure if message is already delivered/failed (per Appwrite docs)

Can you rename the method to updateEmailMessage or can please check the existing naming convention for this api in python/js sdk ?
And show snapshots of executions? @aritracodes-69

@pooranjoyb

Yes so we'll have to maintain the convention, rename it as it is.
